Power efficient receiver architecture

Abstract

Power efficient receiver architectures are described. A receiver includes a first receiver path having a low power consumption compared to a second receiver path with a higher power consumption but a better ability to remove blocking signals. A multiplexer at the output of both receiver paths is used to select the digital bit stream from either the first path or the second path based on whichever path is currently enabled. The first receiver path can be enabled by default until a blocker signal is detected or the received data is invalid. At such an instance, the first receiver path is disabled and the second receiver path is enabled to remove the blocker and read out the data. The second receiver path may then continue to be enabled for a particular number of pings before switching the output back to the first receiver path.
